Rows marked thin have fewer than 20 published prices — shown for completeness, but not enough to call a going rate. “vs Canada” is only filled in where both sides clear that bar.
Road versus trail
Across 5K, 10K and half-marathon entries in Ontario, road races run a median of $61.59 and trail races $67.60. Trail runs about 10% dearer here at the same distances — smaller fields and land-use permits are the usual reason.

How this was counted
Every price is a single entry option on a real race's registration page — not an event-level average, which is what makes a marathon look like it costs $50 because the same weekend sells a $30 kids' run. Team relays, volunteer rows, merchandise and parking are excluded; the platform's mandatory charges are included, because that is what you actually pay.
Races without a confirmed next date are left out entirely: their listed prices come from last year's page and would quietly drag the numbers down. Prices last read August 24, 2026.
